Imouto mode - Automatic scaling

[monele]

I can't believe I can't find it anymore : how does one activate this mode? o_o;... And what's the official name?

[PyTom]

You need to set the RENPY_SCALE_FACTOR environment variable to a number. To make things half as big, for example, you would set RENPY_SCALE_FACTOR=0.5

Thanks ^^. Has this been put in any documentation yet? I search the forum and the doc for "automatic scaling" and "imouto" and found absolutely nothing except discussions about it, but never the exact procedure. Weird.

[PyTom]

No, imouto-mode isn't really documented anywhere. I'm not 100% sure I want to keep supporting it... do you have a really good use-case for it?

[chronoluminaire]

Ooo. Well, now that I know about it, I'd be vaguely tempted to try playing some Ren'Py games on my 640x480 screen WM5 PDA. I know Python exists for Windows Mobile, and I'd guess that dropping a file into some distributed game's game directory containing that one line in an init: block might apply the scaling to the game. Now I just need to figure out how to run Ren'Py in the version of Python that exists for WM, and...

(Feel free to interpret this entire post as saying "No, I don't have a really good use-case for it". )

[PyTom]

I wouldn't expect it to work very well. Apart from Python 2.5 and pygame, we also require a couple of Ren'Py specific modules, _renpy and pysdlsound, to handle graphics and audio, respectively. And those modules have a dozen or so dependencies between them.

do you have a really good use-case for it?

Uuh... no... :'(... Don't kill imouto, pwease! She's done nothing!

I was just thinking I'd like to see my games in 320x240 and/or try some new development on a 640x480 base and see if it would work in 320x240 as well without having to change *everything* (config, pictures, font sizes) constantly.

[PyTom]

Well, I'm not really going to kill it. (6.6 fixes some bugs with it, in fact.) But I'm not sure I want to document it as is...

I'm trying to play a game on my EEE PC (it is the Nettestadt Troll, it's not very old), the screen is 800x480 but the game screen is bigger.

How can I use this imouto mode ? I've tried to modify the options.rpy file, this way :

Code: Select all

        config.screen_width = 800
        config.screen_height = 600
        renpy_scale_factor = 0.7

but it doesn't work at all. I've tried to add the renpy_scale_factor into the script.rpy but it's doesn't work either.

What could I do ?

[monele]

"renpy_scale_factor" must be an environment variable. What OS are you using?

[farvardin]

I'm using linux.

I understand now, so I've typed :

Code: Select all

export RENPY_SCALE_FACTOR=0.7
./NettestadtTroll.sh 

but then the game crashed :

Using scale factor of 0.700000.

renpy.config.window_icon))
TypeError: argument 1 must be pygame.Surface, not Surface

After initialization, but before game start.

EDIT : it's probably because of the Renpy Version, because it worked with another game, but when I copied a newer renpy version over the one for the game, I got the same error, so maybe the game is using a feature uncompatible with the scaling.

[monele]

Sadly, this goes beyond my knowledge :/... We'll have to wait for the author or PyTom to get an in depth analysis ^^;

[PyTom]

That may be a bug in imouto-mode. I'll be fixing it shortly.

[PyTom]

Actually, correction. It was fixed in a previous release... so it's not a problem with current games.

To fix it in the Netteststadt Troll, you'll want to edit renpy/display/core.py, and delete the lines:

Code: Select all

        if renpy.config.window_icon:
            pygame.display.set_icon(
                pygame.image.load(renpy.loader.load(renpy.config.window_icon),
                                  renpy.config.window_icon))

which is found around line 637.

Since we're on the topic I was wondering if imouto mode could be used for scaling some character sprites down during play to create the effect of characters stepping further away but not leaving the room, but without having to create duplicate sprites?
